shadowbutton.h

delphi 开发的自动升级源码

////////////////////////////////////////////////////////////////////
// 类名: CShadowButton
//
// 说明: 类似于原DOS下的阴影效果按钮
//
// 用法:
//       1、把文件shadowbutton.h、shadowbutton.cpp加入工程中
//       2、在使用的对话框中加入头文件，#include shadowbutton.h
//       3、声明要改变的按钮成员变量(可在类向导中进行)，如：
//           CShadowButton	m_Cancel;
//       4、在OnInitDialog()中加入下面语句，进行初始化
//           m_Cancel.SetDefaultFace();
//           m_Cancel.SetDefaultButton();
//
// 修改: 徐景周, 加入PreSubclassWindow()，实现按钮构造时自绘属性.
